【 摘 要 】

This research was conducted in wetlands Semambu Village, District of North Indralaya, Ogan Ilir, South Sumatra Province, Indonesia, which lasted from July 2015 to February 2016. The observation of a microclimate indicate that the average intensity of light outside the auspices of the plot 1968.9 m2s mol1, under waranet 1502.40 mol1m2s, below paranet 721.99 mol1m2s-1and under waranet 439.25 μmol m2s-1- equivalent to the light interception 1 or 100%, 76%, 37% and 22%. Results of soil chemical analysis that the soil has a low fertility study (H2O pH of 3.32, organic C 4.47%, total N 0.35%, Bray P 13.30 ppm, K-ea 0.26 me / 100g, CEC 19.6 rne / 100g and Al-ea 3.28 me / 100g). Tests on 22 genotypes of maize grown with light interception 100%, 76%. 37% and 22%, by calculating tolerance index based on the weight of dry seed cob-1 was found four genotypes of maize tend to be tolerant to low-intensity light that were genotype B 41, Pioneer 27, Sukmaraga and Sugihan. The test results of corn planted in beds shade with light interception 100%, 76%, 37% and 22% for groups of maize tolerant and sensitive, followed by application of urea 0 kg ha1, 100 kg ha-1200 kg ha-1, 300 kg ha-1and 400 kg ha-1indicate that maize and 41 and Pioneer 27 by Urea 300 kg ha-1gives better results than other varieties at different intensities of light oil palm age of 12 years with applications Urea fertilizer 300 kg ha-1, indicating that the B 41 and Pioneer 27 tends to give better results compared with other varieties. The application of a polyculture system palm-maize can produce 1000 kg of dry grain of corn in a 1 ha of oil palm cultivation.
